[web2py] Jessica McKellar talking about windows and the future of Python

[Bruno Rocha]

Hi,

I found this talk interesting
http://www.youtube.com/watch?v=d1a4Jbjc-vU&feature=share

Jessica McKeller talks about how "windows OS" is important to the future of
Python, and how it is complicated to use Python on windows nowadays.

And I think that *web2py is the only framework that does a good job working
on windows*, any other framework has too many problems to run on windows.

So web2py is helping to build the future of Python!

[web2py] Re: [web2py-dev] Re: Spammers on web2pyslices.com

[Bruno Rocha]

Implemented only for user registration, but spammers are registering, so I
guess they have captcha breaking system or there is a hole in the website
security?
 (needs investigation)

The captcha, honeypot, confirm by email or something would be really nice
if implemented in "create a slice" form.

I hope to get some help on this.

Thanks.

[web2py] Spammers on web2pyslices.com

[Bruno Rocha]

Hi,

recently we are having too many spams posted on web2pyslices.com

I am deleting one by one, but started to be difficult to track this.

We need to implement a captcha system or any other kind of spam blocking.

is there any volunter? to do this for user registration form and also for
article post form?

I am in a rush between work and medical treatments, I tried but I really
have no time now to develop this.

If anybody can take this, please email me ans I give you access to the
development version of the code on pythonanywhere.

Thanks.

Re: [web2py] how to start Celery worker in web2py

[Bruno Rocha]

I also would like to see Celery, Solr, Elastic Search and other fantastic
tools working with web2py!

I think this is an important issue and I am sure it is completely easy and
possible to make it.

I personally do not like to use the built-in scheduler, so I am using
python-rq (Redis Queue) for some production sites and it works very well
and offer almost all celery functionalities.

Maybe someone can follow my python-rq[1] example and create a wen2py-celery
tutorial

[1]http://rochacbruno.com.br/web2py-and-redis-queue/

I dont think web2py needs to always reinvent the wheel so I would like to
see more integrations.

wish list:

Whoosh (WIP)
Solr (maybe a haystack clone for web2py)
ElasticSearch
Celery
Thumbor
Neo4J

Re: [web2py] Re: Web2py without fancy wizzard

[Bruno Rocha]

Hello world from scratch

download web2py and unzip it.

create a new app folder  web2py/applications/*hello*

create a model file web2py/applications/hello/*models/model.py
*
# coding: utf-8

from gluon.tools import Auth

db = DAL("sqlite://hello.db")
auth = Auth(db)
auth.define_tables()

db.define_table("hello", Field("world"))

create a controller file in web2py/applications/hello/*
controllers/whatever.py*

#coding: utf-8

def action():
form = SQLFORM(db.hello).process()
return dict(form=form)

create a view file in web2py/applications/hello/*views/whatever/action.html*




  {{=form}}



Now start web2py

python web2py.py

and access your app

http://localhost:8000/hello/whatever/action

Re: [web2py] Performance issues while opening webpage with more than 1 lakh records.....

[Bruno Rocha]

what is your database engine?

we need to see if the bottleneck is in database side.

Place a {{=response.toolbar()}} in your view and paste here the generated
SQL and timings.

Are you using pagination? how many per page? even with 100.000 records, the
grid should use an offset to limit the loaded data.

Re: [web2py] Validator: {Validator1 OR validator2} - Can I get that requires on a Field?

[Bruno Rocha]

Great idea Anthony, CUSTOM can be used in many ways when a builtin
validator does not match the requirements.

I documented this here:
http://rochacbruno.com.br/more-web2py-custom-validators/


@Massimo

Can we include at least the CUSTOM in gluon.validators ?

Re: [web2py] Validator: {Validator1 OR validator2} - Can I get that requires on a Field?

[Bruno Rocha]

It gives me the idea of a CUSTOM validator


class CUSTOM(object):
def __init__(self, function):
self.function = function

def __call__(self, value):
# the function should return the error_message or None
return(value, self.function(value))


So the use should be:

def my_validator_function(value):
 # do anything
 return "error message" or None

db.table.field.requires = CUSTOM(my_validator_function)

So, it works the same as onvalidation but can be applied in models.

results = [validator(value)[1] for validator in self.validators]

else:

return (value, None)


*models/db.py*

*shell*

In [3]: from anyvalidator import ANY

In [4]: ANY([IS_IN_SET(['a','b']), IS_EMAIL()])('m...@test.com')

it is a great idea to include ANY and ALL metavalidators to

Re: [web2py] Re: Converting Field of a SQLFORM.grid to local timezone of a user.....

[Bruno Rocha]

I am on mobile now and I cant ellaborate a good code example, but I can
give you a hint.

db.table.datefield.represent = lambda value, row :
value.strftime("%Y/%m/%d")

grid = SQLFORM.grid(db.table)

so grid will use the represent callback to display the data.

following this example you can do

def set_timezone(value, row):
 return value. #do the calculation

db.table.field.represent = set_timezone

Re: [web2py] Re: SQLite tables not recognised in web2py; even when web2py created them?

[Bruno Rocha]

If your contrib needs to have its own models and controllers, then you
should create it as a plugin. Or you can create a module and define an API
for it, take a dummy example.


/modules/myawesomemodule.py

class MyAwesomeClass(object):
"""
it creates the Awesome object which is a login_method
to use include in your models
db = DAL()
from myawesomemodule import MyAwesomeClass
something = MyAwesomeClass(db)
something.define_tables()
auth.settings.login_methods = something
"""

def __init__(db, *args, **kwargs):
self.db = db

def define_tables(self, migrate=True):
self.table1 = self.db.define_table("table1",
Field("a_field"),
migrate=migrate
)

self.table2 = self.db.define_table("table2",
Field("a_field"),
migrate=migrate
)

def do_something(self):
self.data = self.db(.).select()
# do domething
return data

Then in following your documentation developers should use you module api
as:

models/db.py

db = DAL(.)

from myawesomemodule import MyAwesomeClass

something = MyAwesomeClass(db)
something.define_tables()

auth.settings.login_methods = something

Re: [web2py] Re: SQLite tables not recognised in web2py; even when web2py created them?

[Bruno Rocha]

Usually you create a "script" file in /models/db.py then you define your
tables there, so when starting in shell mode you pass -M

python web2py.py -S yourapp -M

-M run the models/* files and defines your table as "object" for you to
access.

Every framework works in this way.

Optionally, you can use db.executesql("PUT YOUR SQL HERE") and do it by
your own...

[web2py] Real Python for Web Development, featuring web2py

[Bruno Rocha]

Take a look:
http://www.kickstarter.com/projects/1369857650/real-python-for-web-development-featuring-web2py

Why Web2py?

web2py is an open-source web framework for rapid development. You can get
up in running in less than 10 minutes and build a full-featured application
in under an hour. Much like the Python language itself, web2py is designed
for beginners to quickly get up to speed as well as advanced users.

Re: [web2py] DAL and MySQL indexing

Since you have the indexes created on DB backend, The DAL will use this for

Re: [web2py] sending mail to multiple clients

[Bruno Rocha]

I would use sendgrid.com and its awesome newsletter API, alsoi sendgrid
takes care of spamming protection.

I wrote an module to interact with send grid through the API
https://github.com/rochacbruno/pysendgrid

But if you really want to use your own structure you should have a table
with "email", "recipient", "status"

Select 500 of your users which message has not been sent yet, send the
messages, time.sleep(1 hour) and do it again.
for every email sent you go to status table and check the "status" to "sent"

Re: [web2py] Re: web2py world conference 2013

[Bruno Rocha]

I think it is ok to have different dates on each places.

Each country/place can do in preferred data since it is in the same week.

Lets say:

 - May 16 (Thu)
 - May 17 (Fri)
Chicago - May 18 (Sat)
Brasil - May 19 (Sun)

Of course we can have more than one place at the same day, no problem but
we can schedule the days from 16 to 19 May.

My proposal on how it can work:

Each organizer needs a physical room, local advertisement,  Internet
connection, recording equipment.

*Vanue and registration*
The event has to "exist" in a Physical place, people needs to register and
submit proposals on the conference website.

*Funding*
The organizers can sell "sponsorship" or call for funding in order to pay
for event bills (as recording, coffee and lunch) - But this is
responsibility of reach organizer, but all the sponsorship will advertising
on the main website and mailing or other promotion material.

*Proposals*
The proposals will be voted online, people from any place can vote and this
will be used to choose which presentations will be recorded to be included
on the website track.

*The event*
Its a normal local meetup, people goes there, have coffee break and
networking, attend to presentations etc... The only difference is that all
the presentation and activities needs to be recorded in a good audio/video
quality. (optionally transmitted via hangout on air if the place has good
Internet connection)

*The videos:*
Video need to be in a good quality, uploaded to YouTube conference account.
If not presented in English, the video will need to be subtitled to English
using the YouTube (Amara) tools, for this we count on local volunteers.

*The Conference*
Ok, in this case "the conference" will be just a set of videos, organized
in tracks and for each track/video we can have a "forum" like place for
people to interact about that content. So anybody can watch the videos from
other places.


Thats it! 3 or 4 days of local meetups, recorded and putted together on a
"conference" website for everyone to see and interact, also optionally each
meetup can have their local event transmitted alive.


I cannot think on another format.

Re: [web2py] Re: How do I import `gluon.dal` from Python shell?

[Bruno Rocha]

Go to admin interface and click in "Pack All: it generates a .w2p package.

Or just go to your shell and $tar -cvf myapp.tar.gz /path/to/my/app

If you want some more specific package system maybe it is better to put
your app in github and use Fabric, Puppet, Cheff, BUildout or other tools
like this to create a installation recipe.

Re: [web2py] Many to Many relation

[Bruno Rocha]

I can think on two options.

*1. Unique Key*

db.define_table("table",
Field("table_a", "reference table_a"),
Field("table_b", "reference table_b"),
Field("unikey", unique=True, notnull=True, compute=lambda row:
"%(table_a)s-%(table_b)s" % row)
)


*2. Form validator*

def check_unique(form):
if db((db.table.table_a == form.vars.table_a) & (db.table.table_b ==
form.vars.table_b)).count():
form.errors.table_a = "You cannot insert or edit a duplicate
combination"

form = SQLFORM(db.table).process(onvalidation=check_unique)

Mybe it can be implemented as a Field Validator, have to try.

No need to use this module based approach (unless you want), now with

Re: [web2py] Help on Unit Tests

[Bruno Rocha]

There is no official approach, testing is being an issue for a long time,
there was a project called web2py test runner, but the maintainer abandoned
the project.

If you can contribute with something on this subject, your contribution
will be very welcome.

The main problem of testing is the fact that web2py runs its own
environment, for some things this environment depends on "request",
"response" "session" and other state objects which exists only when the
application is running on a webserver.

I think a good test approach would be creating mocks for that objects and
so having a "fake" environment to run the tests on shell.

$ python web2py.py -S appname -M -R /path/tests.py

The above command will open web2py in a shell mode and runs the tests.py
script since the environment is ready, but on this environment we do not
have full "request", "session" and "response" objects, so we need some
mocking for this.

I think the "max" is the first because you can ommit the second.

But I agree this is odd.

Re: [web2py] is bug? sqlform.factory

IS it SQLITE?

Sqlite dos not implements ALTER TABLE for column properties, if you created
the model with n length and so changed it later, sqlite does not respect
this.

It is a sqlite problem.

Re: [web2py] How to automatically send emails to users if they perform an action like sign up...

[Bruno Rocha]

in your models.

mail = auth.settings.mailer
mail.settings.server = "your_smtp_server_and:port"
mail.settings.sender = "y...@you.com"
mail.settings.login = "y...@you.com:password"

# sends an verification e-mail upon registration
auth.settings.registration_requires_verification = True


def send_email(user, subject):
message = """ Multi line string for %(first_name)s.."
message = open("somefile.html", "r").read()
# you also have the option to include everyone in bcc=[...]
mail.send(to=user.email,
   subject=subject,
   message=message % user)


Now in any place like controllers or scripts

users = db(db.auth_user).select()
for user in users:
send_email(user, "some subject")


Dont forget to keep track of sent emails, use try: except... try to not use
gmail for more than 500 recipients.




If you want an email to be send everytime a user login in your page

auth.settings.login_onaccept = lambda form: mail.send(to=form.vars.email,
subject="%(first_name)s logged in" % form.vars, message="User logged in %s"

Yes it is not clear :)

are you trying to create a table inside a table? it is not permitted on
relational dbms. (are you using NOSQL)?

I think you want to create separate tables and create relations?


*BTW: you dont need the trailing ; in Python


db.define_table('post',
 # fields here!
)

db.define_table('Thoughts',
 Field('Editedby', db.auth_user, default=None, readable=True,
writable=True),
Field('TitleOfPost',requires=IS_NOT_EMPTY()),

ON web response you need to use HTML or CSS to break

return string

To a better implementation you should use an ajax callback to the "like"

button, maybe unlike.

I think that for doing this you should modify response.render to a
specialized function.



def my_response_render(*args, **kwargs):
 # here you have to implement what you need
 # and then do the normal response.render


in models/db.py


response.render = my_response_render


In that way you can intercept things before the response get rendered.


** maybe it can be included as a signal in response.render itself.

Yeah it is a problem in THUMB function, thumb function looks for files
under /uploads and you are defining another folder.

change the imageutils module replacing /uploads with /uploads/profile

Re: [web2py] Re: Resizing a user uploaded image

[Bruno Rocha]

I am using this recipe:

http://www.web2pyslices.com/slice/show/1522/generate-a-thumbnail-that-fits-in-a-box

I have plans to integrate it with a JavaScript Cropper plugin to get the
dimensions.
